Abstract: In a wireless network, full duplex communication is established using a half-duplex mechanism. During a full duplex communication opportunity, a first quantum of data is transmitted from a first station to a second station and a second quantum of data is received by the first station from the second station. The full duplex transmission opportunity is implicitly or explicitly established and ended using a transmission mechanism understood by half duplex wireless stations.

Abstract: A method and apparatus for transmitting data are provided. The method includes: when detecting that there is a wireless frame currently being transmitted on a working channel, the first sender estimates a signal attenuation between the first sender and a first receiver for the wireless frame currently being transmitted to obtain an estimation result, and determines a transmitting power of the first sender according to the estimation result; and the first sender sends a wireless frame to a second receiver with the determined transmitting power.

Abstract: A method and system for sending transmission acknowledgement information are disclosed, which relate to the wireless communication field; and solves the problem that full-duplex communication cannot be performed smoothly. The method includes: when a sender completes to send a radio frame to a receiver and needs the receiver to reply transmission acknowledgement information, if the receiver is sending a radio frame to the sender, the receiver replies the transmission acknowledgement information to the sender according to a determined mode for the transmission acknowledgement information. The above technical scheme applies to the WLAN, which achieves a timely data transmission acknowledgement mechanism.

Abstract: The embodiments of the present document provide a method for processing dynamic channel detection, a station and an access point device. The method includes a station transmitting a dynamic channel detection request to an access point and the station deciding whether to use dynamic channel detection according to response information from the access point. The embodiments of the present document enable the station and the access point to negotiate whether to use a dynamic channel detection threshold. This is advantageous in finding the best balance point between improvement of channel utilization and avoidance of collision.

Abstract: Access to a wireless medium is controlled based on contention arbitration. A certain number of wireless devices are allowed to contend for a transmission opportunity. Requests from these wireless devices are processed based on codes contained in the requests. Winning wireless devices are given access to the wireless medium by transmitting a contention arbitration message. In some implementation, codes in the request are selected from an orthogonal or pseudo orthogonal code set.

Abstract: A transmitting wireless device provides channel access information to a receiving wireless device for the receiving wireless device to make a determination of when to transmit and what transmissions parameters to use for the transmission. The channel access information may be used differently by wireless devices operating in a basic service set and an overlapping basic service set. Channel access information may include fields indicative of transmission power used, signal to noise ratio headroom available, and so on. Channel access information may be generated and transmitted at the PHY layer of an implementation, thus providing a fast delivery to the receiving wireless device.
